Environmental impact assessment (EIA) plays a critical role in achieving a balance between urban development and environmental protection. With the rapid growth of the economy and urbanization, effectively evaluating the environmental impacts of development projects and formulating corresponding management strategies have become pressing challenges. Scientifically grounded assessment methods serve as the cornerstone of EIA, with deterministic models forming the core of water environment simulation tools. These tools assess the impacts of pollution sources by simulating changes in water quality and quantity. This study takes Taiwan's environmental impact assessment practices as an example to explore the application of deterministic models, focusing on their effectiveness and limitations across various water bodies such as rivers, watersheds, and reservoirs. The findings reveal that applying scientific models not only enhances understanding of water environment system dynamics but also provides critical support for developing sustainable water management strategies. This study offers a reference framework for future model applications in EIA, contributing significantly to the coordination between urban development and environmental protection.
